With a change in the rules and regulations regarding COVID-19 in the US, tennis fans are hoping that Novak Djokovic will finally be allowed to participate in the upcoming US Open.On Thursday, the Centers for Disease Control and Prevention (CDC), the national public health agency of the United States, released a fresh set of guidelines, lifting a number of restrictions. The highlight of the document was that "unvaccinated people now have the same guidance as vaccinated people."In June, the US Government announced that foreign travelers will be required to show proof of vaccination against the coronavirus to enter the country. This meant that Djokovic, who has decided not to take the jab, was set to miss the entire US Open swing. The Serb had to withdraw from the National Bank Open in Montreal as Canada has similar rules for visitors.Tennis fans, especially those who support the 21-time Grand Slam champion, have suddenly been given hope. Expressing their excitement about the latest developments, people from around the world stated that there was no reason for the authorities and tournament organizers not to allow Djokovic to play."'The Unvaccinated' should be suing governments for discrimination, and on a pack of lies," a fan tweeted.Fang Fang@truthse81193207@EssexPR 'The unvaccinated' should be suing governments for discrimination, and on a pack of lies.492@EssexPR 'The unvaccinated' should be suing governments for discrimination, and on a pack of lies."No excuses now for @usopen @usta to not intervene & help @DjokerNole play #USOpen.
